Glowing in infrared

I got similar results no matter which recipe I used, including a full six-filter image. The right camera shows the same thing: the ridge/crater rim is bright across the whole infrared to red spectrum.

I went back two sols to 032, and found that Oppy had made the same shot, although it only used IR, green, and violet. There were two shots forming a panorama:

What's the difference? Time of day. This image from sol 32 was taken in the morning, about 9:30AM surface time, while the image from sol 34 was taken in late afternoon. I'd say that whatever that material is, it absorbs a lot of heat during the day and radiates it freely. It'd be interesting to have Oppy take a sequence of infrared shots through the night to see how long it radiates, to learn something about the thermal properties of the material.
